LENTO T3

Sound attenuator, insulated with fire-resistant stone wool
  • Insulated with 50 mm thick fire-resistant stone wool
  • In many applications, sound attenuators are installed in fire-resistant insulated duct systems. In applications in which ventilation ducts are to be insulated with 50 mm thick fire-resistant stone wool, the fitter can either install external insulation over the sound attenuator directly at the building site or place an order for the factory-insulated variant. For the LENTO, the factory-insulated variant is available as an accessory.
  • The pressure drop does not change if the LENTO T3 accessory is used.
